● The NS protection function is applicable to grid code VDE-AR-N-4105, SWITZERLAND-
NA/EEA:2020-LV230, EN50549-FI, or ANRE.
● Connect the NS protection switch to GND (pin 16) and DIN5 (pin 18). The switch is
turned on by default. When the switch is turned o, NS protection is triggered. Rapid
shutdown and NS protection use the same pins, which are GND (pin 16) and DIN5 (pin
18). Therefore, you can use only either of the functions.
● The cable connection method for a single inverter is the same as that for cascaded
inverters. For a single inverter, connect GND and DIN5 to the same cable.
● Log in to the FusionSolar app as an installer, choose Me > Device commissioning, and
connect to the WLAN hotspot of the inverter. Log in to the local commissioning system
as an installer, choose Settings > Feature parameters > Dry contact function, and set
Dry contact function to NS protection.
